My Tent Or Yours is still likely to line up for Tuesday's Champion Hurdle, despite an injury scare that caused a spike in his odds on Betfair on Tuesday. Connections were described as "pretty confident" that the horse would be fit to run despite discovery of a puncture wound in the middle of one of his soles.

"It's a little puncture, right in the middle of the [front left] sole," said Nicky Henderson, trainer of My Tent Or Yours. "It's a bad spot, as you can't really put a pad on it. It's clean and it now needs 24 hours to harden off and then we'll see where we are. When we changed his shoe, he was in some discomfort, but his shoe is now back on.

"I would suspect there's every possibility he'll have a swim [on Wednesday], as opposed to a canter, but that doesn't worry me one iota. The good thing is, he's done all of his work. He did a nice bit of work on Saturday and has missed nothing.

"These sort of scares happen all the time and we would be very, very unlucky if this goes on and on." Henderson guessed that the injury must have occured on Monday but offered no clue as to what may have caused it.

Frank Berry, who speaks for JP McManus, the owner of My Tent Or Yours, said his impression from talking to Henderson was that the trainer was "pretty confident" that the horse would be able to run in the big race on the Cheltenham Festival's opening day. He confirmed that Tony McCoy would replace Barry Geraghty on Jezki, also owned by McManus, if My Tent Or Yours were unable to run.

My Tent Or Yours is the 9-2 third-favourite for the Champion Hurdle with most conventional bookmakers but his odds doubled to 10-1 on Betfair as news of his injury broke. They gradually shortened through the day, settling around 11-2 last night. William Hill cut Jezki to 7-1 from 10s, while pushing My Tent Or Yours to 5-1.

It is nothing new for late doubts to exist about the participation of Henderson-trained horses in the Champion Hurdle. Binocular was ruled out of the 2010 race, only to win it after connections performed a U-turn, while the same horse was a late withdrawal from the 2011 race when medication failed to clear his system in time.

"They're not payers," Curley said after a Cheltenham Festival preview evening in Galway on Monday night. He had used his platform at the event to confirm his involvement in the January coup, his first public pronouncement on the matter. Asked if he intended to pursue Jennings over the money won, he said: "If it takes a million, we'll get it".

Despite repeated requests through various channels, Jennings Bet, which is registered in the Isle of Man, offered no response to Curley's criticisms on Tuesday.

A spokesman for the Isle of Man Gambling Supervision Commission said it was not allowed to confirm or deny whether a complaint had been made against any licensee.

No Nay Never, the American-trained horse that won at Royal Ascot last year, is likely to have his sights lowered when he returns to this year's Royal meeting. Wesley Ward, his trainer, said on Tuesday that he was now aiming at the Group Three Jersey Stakes rather than the St James's Palace Stakes, a Group One, for the colt, who lost his unbeaten record on his seasonal reappearance at Gulfstream on Saturday, a race Ward had expected him to win easily.
